The second most popular Data Link layer standard for local area networking. It implements the token passing method of arbitrating multiple-computer access to the same network. It operates at either 4 or 16 Mbps. FDDI is similar to Token Ring and operates at 100Mbps.
A local area network developed by IBM. It is a computer network configuration in which all the computers are arranged on a ring. A token, which is a specific bit pattern, travels around the ring. To send a message, the host must be in receipt of the token; this is attached to each message that is sent. Once the host has completed its transmission the token is then released, until the next host requiring service. This process continues and is used as the basis for contention resolution. Token Ring is more deterministic than Ethernet, it ensures that all users obtain regular turns at transmitting their data. With Ethernet, all users compete to get onto the network. Token Ring is a data link protocol (MAC layer protocol) and works at layers 1 and 2 of the OSI model.

networking: A set of rules, developed by IBM, for exchanging information between computers that are connected with cables. Token ring networks can operate at speeds of 4 or 16 megabits per second, which are many times faster than normal AppleTalk networks. The token is actually a packet (like a small envelope) that is passed from computer to computer around the ring. If a computer has nothing to say, it passes the token on to the next computer. This strategy eliminates data collisions, which is what happens when two computers talk at the exact same time.

A type of local area network in which the workstations relay a packet of data called a token in a logical ring configuration. When a station wants to transmit, it takes possession of the token, attaches it= s data, then frees the token after the data has made a complete circuit of the electrical ring.
